When you think of emotional support animals, cold-blooded alligators probably aren't the first thing that comes to mind.

But Wally, a 3-year-old, 4.5-feet-long reptile, plies his trade doing exactly that, and earlier this week, took some time out of his busy schedule to pay a visit to a senior living facility in Pennsylvania and offer some comfort.

His owner, Joie Henney, took Wally to SpiriTrust Lutheran Village in York, Pennsylvania, on Monday, FOX 13 reported.

A few residents were hesitant to get close to Wally but Henney encouraged them to get to know the friendly reptile.

"I'm not scared of snakes but that thing has a lot of teeth,” a resident told the York Daily Record.

Wally went to live with Henney at his residence in Strinestown, Pennsylvania, in September 2015 when the reptile was 14 months old. The owner said Wally was “afraid of everything” but started to adjust after some time.

"He was like a little puppy dog," Henney told the York Daily Record. "He would follow us around the house."

Henney said Wally likes to watch television and his favorite movie is “The Lion King.” The alligator lives in a 300-gallon pond with his fellow gator Scrappy, who is 2 years old.

The owner said Wally has “never bitten” him and is a calm alligator.

“Wally’s never bitten me and he’s never tried to bite anyone. He’s pretty laid-back,” he said.
